Islam is world’s most common state religion — study

Pew Research Center analysis of data from 199 countries finds 4 in 10 have officially endorsed faiths or preferred faiths

Islam is the world’s most common state-endorsed religion, according to a Pew Research Center study published Tuesday.

Of the 199 countries covered in the survey, 43 designate a particular faith as its official state religion. Twenty-seven countries enshrine Islam as its official religion, compared to 13 countries that do the same for Christianity.

However, of the 40 governments that unofficially favor a particular religion, 28 of them give clear preference to Christianity, the study said.

Over 80 countries, or 4 in 10, have official government faiths or preferred faiths.

Israel is the only country whose state religion is Judaism. Several countries including Russia, Lithuania and Serbia include Judaism as one of their “traditional” favored religions along with Christianity.

The majority of governments, though, are what Pew referred to as “neutral” toward religion. Over 100 of them have no official or preferred religion. These include the United States, which gives benefits to particular religious groups, but “generally does so without systematically favoring a specific group over others,” researchers said.
